Notes :
ITEM DEFINITION
Airframe the airplane is an all metal, four-place, high wing, single engine airplane equipped with
tricycle landing gear and is designed for general UTILITY purposes.
Fuselage semi-monocoque covered with aluminum skin
Empennage (tail assembly) consists of conventional vertical stabilizer, rudder, horizontal stablizer and
elevator
Landing Gear tricycle type with steerable nose wheel. Shock absorption is provided by the tubular spring-
steel main landing gear struts and the air/oil nose gear shock strut. Each main gear wheel is
equipped with a hydraulically actuated disk-type brake on the inboard side of each week
Brakes single-disc, hydraulically-actuated brake on each main landing gear wheel
Engine horizontally opposed, four -cylinder, overhead valve, air-cooled, carburetor engine with wet
sump oil system
Ignition engine ignition is provided by two-engine driven magnetos and spark plugs in each cylinder
Wing Flaps single-slot type and are electronically operated by a motor located in the right wing
Carburetor Up-draft, float-type, fixed jet carburetor mounted on the bottom of the engine
Propeller Two bladed, fixed pitch, one-piece forged aluminum alloy propeller which is anodized to
retard corrosion.
Master Switch Split-rocker type switch, labeled BAT on the right and ALT on left half
Ground Control Nose wheel can turn up to 30° either side when differential braking is used, 10° if none.
Other Notes :
- The ELT consists of a self-contained dual-frequency radio transmitter and battery power supply, and is activated
by an impact of 5g or more as may be experienced in a crash landing.
- The ELT will provide line-of-sight transmission up to 100 miles at 10,000 feet.
- Duration of ELT transmission is affected by ambient temperature.
+21°C to +54°C = 115 hours continuous transmission
-40°C = 70 hrs
- Located at the baggage compartment wall (Color Orange)
ELT Operation.
1. ENSURE ELT ACTIVATION - Listen to transceiver if it transmits to 121.5/243.0. If not, set ELT to “ON” position and
verify by listening to transceiver
2. PRIOR TO SIGHTINGS RESCUE AIRCRAFT - Conserve battery. Don’t use transceiver
3. AFTER SIGHTINGS RESCUE AIRCRAFT - Set ELT to “OFF”, preventing radio interference. If resuce aircrfat can’t
locate crash site, set it to on again.
4. FOLLOWING RESCUE - Once crash shite is located, turn “OFF” ELT.
